the macro timer gets reset every time yeh hit the button.
The way it works if if yeh havent hit that button for 20 seconds it resets.
what might work better is

/castrandom shockwave,thunder clap,devastate,

make sure yeh keep the trailing comma in

I just recently started playing with macaroon

uncheck every yeh checked?

I guess yer trying to set it up so that it changes when yeh have different stances?
